Preheat the oven to broil and start a pot of pasta water to boil.
Lay the prosciutto on a baking sheet and broil until crisp - about 2-3 minutes. Do not walk away this goes quickly. Remove the prosciutto and let it cool a bit on the sheet. When cool enough to handle, cut or break it into bite sized pieces.
Cook pasta according to directions and scoop it out into a large bowl.
Add the arugula, balsamic vinegar and olive oil and salt and pepper to the pasta in the bowl and toss to combine. Don't add too much salt, the prosciutto will be salty.
Serve topped with the prosciutto and freshly grated parmesan cheese.
Notes
Baby arugula - can use baby spinach or kale. You want a baby green so that it will wilt with just the heat of the pasta.Prosciutto - can use cooked pancetta or bacon.
